In the last few years, surprising new developments in neuroscience, environmental psychology, biology, mathematics, and other fields have begun to challenge designers to think differently about their role, particularly as we seek to transition to a world of healthier and more resilient environments. Science reveals the essential geometrical and sensorial qualities that create spaces promoting healing and life. Diagnostic tools such as eye-tracking and Visual Simulation Software also show that many pieces of the built environment are either invisible to the unconscious, or they create anxiety. Leading researchers and authors will discuss many of these findings, and their sometimes provocative implications.
